RESUMO

Waste electrical and electronic equipment (WEEE) is one of the world's fastest-growing class of waste. WEEE contain a large amount of precious materials that have aroused the interest to develop new recycling technologies. Hence, effective recycling strategies are extremely necessary to promote the proper handling of these materials as well as for environmentally sound recovery of secondary raw resource. This paper reviews important existing methods and emerging technologies in WEEE management, with special emphasis in characterization, extraction and reclamation of precious materials from waste computer and mobile phones. Traditional pyrometallurgical and hydrometallurgical technologies still play a central role in the recovery of metals. More recently, emerging greener recycling technologies using microorganisms (i.e. biometallurgical), plasma arc fusion method and pretreatments (i.e. ultrasound and mechanochemical technologies) combined with other recycling methods (e.g. hydrometallurgical), and using less toxic solvents such as ionic liquids (ILs) and deep eutectic solvents (DESs) have also been attempted to recycle metals from computer and mobile phone scrap. The role of analytical method development, especially using spectroanalytical methods for chemical inspection and e-waste sorting process at industrial applications is also discussed. This confirmed that most direct sampling techniques such as laser-induced breakdown spectroscopy (LIBS) and X-ray fluorescence (XFR) have several advantages over traditional sorting methods including rapid analytical response, without use of chemical reagents or waste generation, and greater reclamation of precious and critical materials in the WEEE stream.

RESUMO

The increase in production of biobased plastics as a replacement for fossil fuel-based plastics has created the need for studies to assess their degradation under various conditions. However, developing reliable laboratory and field-testing protocols for biobased materials and products still requires extensive research. In this study, the biodegradability of a biocomposite consumer product, smart cellphone case, was determined under laboratory scale anaerobic (38 °C) and composting assays (58 °C) as well as under field scale (60-67 °C) composting conditions. The laboratory scale composting assay was conducted for 46 days using cellphone cases with dimensions of 7 × 3.5 × 0.2 and 4.6 × 3.5 × 0.2 cm, which achieved approximately 20% biodegradation. The field scale composting conditions achieved 55% weight loss of cellphone cases in 80 days. The subsequent anaerobic biodegradation assays contained three different sized (grinded, cut into 2 × 2 × 0.2 and 4 × 4 × 0.2 cm pieces) biocomposite cellphone cases conducted under mesophilic conditions for 169 days. Among the conditions tested, the size of cellphone cases did not cause a significant difference in biodegradation under anaerobic conditions. Anaerobic digestion conditions yielded only 6-8% biodegradation, which was significantly lower than that of composting. The results agree with literature on conventional waste streams stating that aerobic microbial processes are more effective to break down complex substrates, similar to biocomposite cellphone cases tested, than their anaerobic counterparts.

RESUMO

With the rapidly increasing popularity of 5G mobile technology, the effect of radiofrequency radiation on human health has caused public concern. This study explores the effects of a simulated 3.5 GHz radiofrequency electromagnetic radiation (RF-EMF) environment on the development and microbiome of flies under intensities of 0.1 W/m2, 1 W/m2 and 10 W/m2. We found that the pupation percentages in the first 3 days and eclosion rate in the first 2 days were increased under exposure to RF-EMF, and the mean development time was shortened. In a study on third-instar larvae, the expression levels of the heat shock protein genes hsp22, hsp26 and hsp70 and humoral immune system genes AttC, TotC and TotA were all significantly increased. In the oxidative stress system, DuoX gene expression was decreased, sod2 and cat gene expression levels were increased, and SOD and CAT enzyme activity also showed a significant increase. According to the 16S rDNA results, the diversity and species abundance of the microbial community decreased significantly, and according to the functional prediction analysis, the genera Acetobacter and Lactobacillus were significantly increased. In conclusion, 3.5 GHz RF-EMF may enhance thermal stress, oxidative stress and humoral immunity, cause changes in the microbial community, and regulate the insulin/TOR and ecdysteroid signalling pathways to promote fly development.

RESUMO

BACKGROUND: Non-adherence to Tuberculosis (TB) medication is a serious threat to TB prevention and control programs, especially in resource-limited settings. The growth of the popularity of mobile phones provides opportunities to address non-adherence, by facilitating direct communication more frequently between healthcare providers and patients through SMS texts and voice phone calls. However, the existing evidence is inconsistent about the effect of SMS interventions on TB treatment adherence. Such interventions are also seldom developed based on appropriate theoretical foundations. Therefore, there is a reason to approach this problem more rigorously, by developing the intervention systematically with evidence-based theory and conducting the trial with strong measurement methods. METHODS: This study is a single-blind parallel-group design individual randomized control trial. A total of 186 participants (93 per group) will be individually randomized into one of the two groups with a 1:1 allocation ratio by a computer-generated algorithm. Group one (intervention) participants will receive daily SMS texts and weekly phone calls concerning their daily medication intake and medication refill clinic visit reminder and group two (control) participants will receive the same routine standard treatment care as the intervention group, but no SMS text and phone calls. All participants will be followed for two months of home-based self-administered medication during the continuation phases of the standard treatment period. Urine test for the presence of isoniazid (INH) drug metabolites in urine will be undertaken at the random point at the fourth and eighth weeks of intervention to measure medication adherence. Medication adherence will also be assessed by self-report measurements using the AIDS Clinical Trial Group adherence (ACTG) and Visual Analogue Scales (VAS) questionnaires, and clinic appointment attendance registration. Multivariable regression model analysis will be employed to assess the effect of the Ma-MAS intervention at a significance level of P-value < 0.05 with a 95% confidence interval. DISCUSSION: For this trial, a mobile-assisted medication adherence intervention will first be developed systematically based on the Medical Research Council framework using appropriate behavioural theory and evidence. The trial will then evaluate the effect of SMS texts and phone calls on TB medication adherence. Evidence generated from this trial will be highly valuable for policymakers, program managers, and healthcare providers working in Ethiopia and beyond. TRIAL REGISTRATION: The trial is registered in the Pan-Africa Clinical Trials Registry with trial number PACTR202002831201865.

RESUMO

The use of GPS positioning and navigation capabilities in mobile phones is present in our daily lives for more than a decade, but never with the centimeter level of precision that can actually be reached with several of the most recent smartphones. The introduction of the new GNSS systems (Global Navigation Satellite Systems), the European system Galileo, is opening new horizons in a wide range of areas that rely on precise georeferencing, namely the mass market smartphones apps. The constant growth of this market has brought new devices with innovative capabilities in hardware and software. The introduction of the Android 7 by Google, allowing access to the GNSS raw code and phase measurements, and the arrival of the new chip from Broadcom BCM47755 providing dual frequency in some smartphones came to revolutionize the positioning performance of these devices as never seen before. The Xiaomi Mi8 was the first smartphone to combine those features, and it is the device used in this work. It is well known that it is possible to obtain centimeter accuracy with this kind of device in relative static positioning mode with distances to a reference station up to a few tens of kilometers, which we also confirm in this paper. However, the main purpose of this work is to show that we can also get good positioning accuracy using long baselines. We used the ability of the Xiaomi Mi8 to get dual frequency code and phase raw measurements from the Galileo and GPS systems, to do relative static positioning in post-processing mode using wide baselines, of more than 100 km, to perform precise surveys. The results obtained were quite interesting with RMSE below 30 cm, showing that this type of smartphone can be easily used as a low-cost device, for georeferencing and mapping applications. This can be quite useful in remote areas where the CORS networks are not dense or even not available.

RESUMO

During the COVID-19 pandemic, US populations have experienced elevated rates of financial and psychological distress that could lead to increases in suicide rates. Rapid ongoing mental health monitoring is critical for early intervention, especially in regions most affected by the pandemic, yet traditional surveillance data are available only after long lags. Novel information on real-time population isolation and concerns stemming from the pandemic's social and economic impacts, via cellular mobility tracking and online search data, are potentially important interim surveillance resources. Using these measures, we employed transfer function model time-series analyses to estimate associations between daily mobility indicators (proportion of cellular devices completely at home and time spent at home) and Google Health Trends search volumes for terms pertaining to economic stress, mental health, and suicide during 2020 and 2021 both nationally and in New York City. During the first pandemic wave in early-spring 2020, over 50% of devices remained completely at home and searches for economic stressors exceeded 60,000 per 10 million. We found large concurrent associations across analyses between declining mobility and increasing searches for economic stressor terms (national proportion of devices at home: cross-correlation coefficient (CC) = 0.6 (p-value <0.001)). Nationally, we also found strong associations between declining mobility and increasing mental health and suicide-related searches (time at home: mood/anxiety CC = 0.53 (<0.001), social stressor CC = 0.51 (<0.001), suicide seeking CC = 0.37 (0.006)). Our findings suggest that pandemic-related isolation coincided with acute economic distress and may be a risk factor for poor mental health and suicidal behavior. These emergent relationships warrant ongoing attention and causal assessment given the potential for long-term psychological impact and suicide death. As US populations continue to face stress, Google search data can be used to identify possible warning signs from real-time changes in distributions of population thought patterns.

RESUMO

Objective: To investigate the direct impact of exposure of the scrotum to 4G cellphone radiofrequency electromagnetic radiation (RF-EMR) on the testis of adult rats. METHODS: We equally randomized 30 adult male SD rats into a control and an exposure group, the latter exposed to 4G cellphone RF-EMR 6 hours a day for 150 days. Then, we analyzed the changes in semen quality and seminiferous epithelia, and measured the levels antioxidant enzyme-peroxide and the expressions of blood-testis barrier proteins in the testis of the rats. RESULTS: Compared with the controls, the rats in the exposure group showed significantly decreased sperm concentration (ï¼»6.39 ± 0.82ï¼½ vs ï¼»4.74 ± 0.87ï¼½ ×107/ml, P < 0.05), viability (ï¼»62.11 ± 8.82ï¼½% vs ï¼»41.44 ± 7.33ï¼½%, P < 0.05), motility (ï¼»55.71 ± 7.39ï¼½ vs ï¼»36.22 ± 6.36ï¼½%, P < 0.05), the percentage of morphologically normal sperm (ï¼»84.89 ± 5.11ï¼½% vs ï¼»70.78 ± 8.11ï¼½%, P < 0.05) and Johnsen's score (8.38 ± 0.98 vs 6.11 ± 1.56, P < 0.05), increased Coentino's score (1.36 ± 0.21 vs 1.81 ± 0.34, P < 0.05) and MDA level (P < 0.05), reduced levels of SOD, GSH and CAT (P < 0.05), and down-regulated expressions of occludin, ZO-1, CAR and N-Cadherin (P < 0.05). CONCLUSIONS: Exposure of the scrotum to 4G cellphone RF-EMR directly causes injury of the testis, disorder of the blood-testis barrier, reduction of semen quality and consequently decline in the fertility of male rats.

RESUMO

BACKGROUND: Young adults' early adoption of new cell phone technologies have created challenges to survey recruitment but offer opportunities to combine random digit dialing (RDD) sampling with web mode data collection. The National Young Adult Health Survey was designed to test the feasibility of this methodology. OBJECTIVE: In this study, we compared response rates across the telephone mode and web mode, assessed sample representativeness, examined design effects (DEFFs), and compared cigarette smoking prevalence to a gold standard national survey. METHODS: We conducted a survey experiment where the sampling frame was randomized to single-mode telephone interviews, telephone-to-web sequential mixed mode, and single-mode web survey. A total of 831 respondents aged 18 to 34 years were recruited via RDD at baseline. A soft launch was conducted prior to main launch. We compared the web mode to the telephone modes (ie, single-mode and mixed mode) at wave 1 based on the American Association for Public Opinion Research response rate 3 for screening and extended surveys. Base-weighted demographic distributions were compared to the American Community Survey. The sample was calibrated to the US Census Bureau's American Community Survey to calculate DEFFs and to compare cigarette smoking prevalence to the National Health Interview Survey. Prevalence estimates are estimated with sampling weights and are presented with unweighted sample sizes. Consistency of estimates was judged by 95% CI. RESULTS: The American Association for Public Opinion Research response rate 3 was higher in the telephone mode than in the web mode (24% and 30% vs 6.1% and 12.5%, for soft launch and main launch, respectively), which was reflected in response rate 3 for screening and extended surveys. During the soft launch, the extended survey and eligibility rate were low for respondents pushed to the web mode. To boost productivity and survey completes for the web condition, the main launch used cell phone numbers from the sampling frame where the sample vendor matched the number to auxiliary data, which suggested that the number likely belonged to an adult in the target age range. This increased the eligibility rate, but the screener response rate was lower. Compared to population distribution from the US Census Bureau, the telephone mode overrepresented men (57.1% [unweighted n=412] vs 50.9%) and those enrolled in college (40.3% [unweighted n=269] vs 23.8%); it also underrepresented those with a Bachelor of Arts or Science (34.4% [unweighted n=239] vs 55%). The web mode overrepresented White, non-Latinos (70.7% [unweighted n=90] vs 54.4%) and those with some college education (30.4% [unweighted n=40] vs 7.6%); it also underrepresented Latinos (13.6% [unweighted n=20] vs 20.7%) and those with a high school or General Education Development diploma (15.3% [unweighted n=20] vs 29.3%). The DEFF measure was 1.28 (subpopulation range 0.96-1.93). The National Young Adult Health Survey cigarette smoking prevalence was consistent with the National Health Interview Survey overall (15%, CI 12.4%-18% [unweighted 149/831] vs 13.5%, CI 12.3%-14.7% [unweighted 823/5552]), with notable deviation among 18- to 24-year-olds (15.6%, CI 11.3%-22.2% [unweighted 51/337] vs 8.7%, CI 7.1%-10.6% [unweighted 167/1647]), and those with education levels lower than Bachelor of Arts or Science (24%, CI 19.3%-29.4% [unweighted 123/524] vs 17.1%, CI 15.6%-18.7% [unweighted 690/3493]). CONCLUSIONS: RDD sampling for a web survey is not feasible for young adults due to its low response rate. However, combining this methodology with RDD telephone surveys may have a great potential for including media and collecting autophotographic data in population surveys.

RESUMO

The transmission of COVID-19 is dependent on social mixing, the basic rate of which varies with sociodemographic, cultural, and geographic factors. Alterations in social mixing and subsequent changes in transmission dynamics eventually affect hospital admissions. We employ these observations to model and predict regional hospital admissions in Sweden during the COVID-19 pandemic. We use an SEIR-model for each region in Sweden in which the social mixing is assumed to depend on mobility data from public transport utilisation and locations for mobile phone usage. The results show that the model could capture the timing of the first and beginning of the second wave of the pandemic 3 weeks in advance without any additional assumptions about seasonality. Further, we show that for two major regions of Sweden, models with public transport data outperform models using mobile phone usage. We conclude that a model based on routinely collected mobility data makes it possible to predict future hospital admissions for COVID-19 3 weeks in advance.

RESUMO

BACKGROUND: Mobile-phone reminders have gained traction among policymakers as a way to improve childhood vaccination coverage and timeliness. However, there is limited evidence on the acceptability of mobile-phone reminders among patients and caregivers. This systematic review and meta-analysis aimed to evaluate the ownership of mobile-phone device and the willingness to receive mobile-phone reminders among mothers/caregivers utilizing routine childhood immunization services in Nigeria. METHOD: MEDLINE, Scopus, CINAHL, CNKI, AJOL (African Journal Online), and Web of Science were systematically searched for studies on the acceptability of mobile-phone reminders for routine immunization appointments among mothers/caregivers in Nigeria. Studies were assessed for methodological quality using the Newcastle Ottawa Scale and JBI critical appraisal checklists. Meta-analysis was conducted using random-effects model to generate pooled estimates (proportion) of mothers who owned at least one mobile phone and proportion of mothers willing to receive mobile-phone reminders. RESULTS: Sixteen studies (13 cross-sectional and three interventional) involving a total of 9923 mothers across 15 states and the Federal Capital Territory Abuja met inclusion criteria. Pooled estimates showed that the proportion of mothers who owned at least one mobile phone was 96.4% (95% CI = 94.1-98.2%; I2 = 96.3%) while the proportion of mothers willing to receive mobile-phone reminders was 86.0% (95% CI = 79.8-91.3%, I2 = 98.4%). Most mothers preferred to receive text message reminders at least 24 h before the routine immunization appointment day, and in the morning hours. Approximately 52.8% of the mothers preferred to receive reminders in English, the country's official language. CONCLUSION: Current evidence suggests a high acceptability for mobile-phone reminder interventions to improve routine childhood immunization coverage and timeliness. Further studies, however, are needed to better understand unique regional preferences and assess the operational costs, long-term effects, and risks of this intervention.

RESUMO

The COVID-19 pandemic has created urgent demand for timely data, leading to a surge in mobile phone surveys for tracking the impacts of and responses to the pandemic. Using data from national phone surveys implemented in Ethiopia, Malawi, Nigeria and Uganda during the pandemic and the pre-COVID-19 national face-to-face surveys that served as the sampling frames for the phone surveys, this paper documents selection the biases in individual-level analyses based on phone survey data. In most cases, individual-level data are available only for phone survey respondents, who we find are more likely to be household heads or their spouses and non-farm enterprise owners, and on average, are older and better educated vis-a-vis the general adult population. These differences are the result of uneven access to mobile phones in the population and the way that phone survey respondents are selected. To improve the representativeness of individual-level analysis using phone survey data, we recalibrate the phone survey sampling weights based on propensity score adjustments that are derived from a model of an individual's likelihood of being interviewed as a function of individual- and household-level attributes. We find that reweighting improves the representativeness of the estimates for phone survey respondents, moving them closer to those of the general adult population. This holds for both women and men and for a range of demographic, education, and labor market outcomes. However, reweighting increases the variance of the estimates and, in most cases, fails to overcome selection biases. This indicates limitations to deriving representative individual-level estimates from phone survey data. Obtaining reliable data on men and women through future phone surveys will require random selection of adult interviewees within sampled households.

RESUMO

BACKGROUND: One way to improve the delivery of oncology palliative care in low and middle-income countries (LMICs) is to leverage mobile technology to support healthcare providers in implementing pain management guidelines (PMG). However, PMG are often developed in higher-resourced settings and may not be appropriate for the resource and cultural context of LMICs. OBJECTIVES: This research represents a collaboration between the University of Virginia and the Nepalese Association of Palliative Care (NAPCare) to design a mobile health application ('app') to scale-up implementation of existing locally developed PMG. METHODS: We conducted a cross-sectional survey of clinicians within Nepal to inform design of the app. Questions focused on knowledge, beliefs, and confidence in managing cancer pain; barriers to cancer pain management; awareness and use of the NAPCare PMG; barriers to smart phone use and desired features of a mobile app. FINDINGS: Surveys were completed by 97 palliative care and/or oncology healthcare providers from four diverse cancer care institutions in Nepal. 49.5% (n = 48) had training in palliative care/cancer pain management and the majority (63.9%, n = 62) reported high confidence levels (scores of 8 or higher/10) in managing cancer pain. Highest ranked barriers to cancer pain management included those at the country/cultural level, such as nursing and medical school curricula lacking adequate content about palliative care and pain management, and patients who live in rural areas experiencing difficulty accessing healthcare services (overall mean = 6.36/10). Most nurses and physicians use an Android Smart Phone (82%, n = 74), had heard of the NAPCare PMG (96%, n = 88), and reported frequent use of apps to provide clinical care (mean = 6.38/10, n = 92). Key barriers to smart phone use differed by discipline, with nurses reporting greater concerns related to cost of data access (70%, n = 45) and being prohibited from using a mobile phone at work (61%; n = 39). CONCLUSIONS: Smart phone apps can help implement PMG and support healthcare providers in managing cancer pain in Nepal and similar settings. However, such tools must be designed to be culturally and contextually congruent and address perceived barriers to pain management and app use.

RESUMO

BACKGROUND: As the vast majority of women who present in threatened preterm labour (TPTL) will not deliver early, clinicians need to balance the risks of over-medicalising the majority of women, against the potential risk of preterm delivery for those discharged home. The QUiPP app is a free, validated app which can support clinical decision-making as it produces individualised risks of delivery within relevant timeframes. Recent evidence has highlighted that clinicians would welcome a decision-support tool that accurately predicts preterm birth. METHODS: Qualitative interviews were undertaken as part of the EQUIPTT study (The Evaluation of the QUiPP app for Triage and Transfer) (REC: 17/LO/1802) which aimed to evaluate the impact of the QUiPP app on management of TPTL. Individual semi-structured telephone interviews were used to explore clinicians' (obstetricians' and midwives') experiences of using the QUiPP app and how it was implemented at their hospital sites. Thematic analysis was chosen to explore the meaning of the data, through a framework approach. RESULTS: Nineteen participants from 10 hospital sites in England took part. Data analysis revealed three overarching themes which were: 'experience of using the app', 'how QUiPP risk changes practice' and 'successfully adopting QUiPP: context is everything'. With these final themes we appeared to have achieved our aim of exploring the clinicians' experiences of using and implementing the QUiPP app. CONCLUSION: This study explored different clinician's experiences of implementing the app. The organizational and cultural context at different sites appeared to have a large impact on how well the QUiPP app was implemented. Future work needs to be undertaken to understand how best to embed the intervention within different settings. This will inform scale up of QUiPP app use across the UK and ensure that clinicians have access to this free, easy-to-use tool which can positively aid clinical decision making when caring for women in TPTL.

RESUMO

OBJECTIVE: Mobile phones are used in research studies, to enroll and follow-up participants, collect data, and implement mHealth initiatives. We conducted a longitudinal study in a birth cohort, where infants were required to make four scheduled visits by 12 months of age. Families of those failing to attend scheduled follow-up visits, were contacted telephonically to ascertain the reasons, which were categorized as: not interested to continue participating, migrated, phone disconnected due to telecom change, or other reason. RESULTS: A total of 413 mother-infant dyads were enrolled. The overall attrition was 56%, with majority occurring at the first follow-up visit. This temporally coincided with a telecom service provider announcing strong incentives to switch providers. Attrition monotonically decreased at subsequent visits. The reasons were: moved away (13%), no longer interested (8%), phone disconnected (7%), and multiple other reasons (28%), the majority of whom had unreachable phones. Those who remained in the study and those lost to follow-up were similar on most demographic variables. Among common reasons for attrition in cohort studies, we experienced a new dimension introduced by telecom changes. These findings underscore the need to consider unexpected reasons for attrition in longitudinal studies, and design more robust methods to follow-up participants.

RESUMO

Introducción: el uso de teléfonos inteligentes se ha asociado significativamente con una disminución para el aprendizaje y las tareas relacionadas con el trabajo, incluidas aquellas tareas asociadas con el entorno de atención sanitaria. En México el uso de dispositivos móviles ha aumentado exponencialmente y se ha estimado hasta un 75% de los encuestados poseen algún grado de atención a estos dispositivos. Asimismo, la dependencia a estos dispositivos ha sido asociada con adicción a sustancias como el alcohol, tabaco, marihuana entre otros. En el ámbito sociosanitario puede afectar el desempeño mental, la concentración en la realización de los cuidados y en general para los estudiantes de enfermería presentar distracciones en la práctica.

Introduction: smartphone use has been significantly associated with a decline in learning and work-related tasks, including those tasks associated with the healthcare environment. In Mexico, the use of mobile devices has increased exponentially, and it has been estimated that up to 75% of those surveyed have some degree of attention to these devices. Likewise, dependence on these devices has been associated with addiction to substances such as alcohol, tobacco, marijuana, among others. In the socio-sanitary field, it can affect mental performance, concentration in the realization of care and in general for nursing students present distractions in practice. Objective. Identify the level of dependence on the mobile phone and relate it to risk behaviors such as addiction to legal and illegal substances. Methodology. Descriptive, cross-sectional, and observational study. Results. 84.3% state that someone close to them has called them dependent on the mobile phone, 74% were in medium dependence and 22.3% in high dependence, associations were found through Rho and OR, with the consumption of alcohol, tobacco, and other drugs. Conclusion. Mobile phone dependence in students was generally characterized as a medium and high NE | 05level and positive correlations were found for tobacco and other drug use[AU]


Introdução: o uso de smartphone foi significativamente associado a um declínio no aprendizado e nas tarefas relacionadas ao trabalho, incluindo aquelas associadas ao ambiente de saúde. No México, o uso de dispositivos móveis aumentou exponencialmente e estima-se que até 75% dos pesquisados têm algum grau de atenção a esses dispositivos. Da mesma forma, a dependência desses dispositivos tem sido associada à dependência de substâncias como álcool, tabaco, maconha, entre outras. No campo sociossanitário, pode afetar o desempenho mental, a concentração na realização do cuidado e em geral para os alunos de enfermagem apresentarem distrações na prática. Objetivo. Identifique o nível de dependência do telefone celular e relacione-o a comportamentos de risco, como dependência de substâncias legais e ilegais. Metodologia. Estudo descritivo, transversal e observacional. Resultados. 84,3% afirmam que alguém próximo os chamou de dependente do celular, 74% estavam em média dependência e 22,3% em alta dependência, foram encontradas associações por meio de Rho e OR, com o consumo de álcool, tabaco e outras drogas. Conclusão. A dependência de telefone celular em estudantes foi geralmente caracterizada como um nível médio e alto e foram encontradas correlações positivas para o uso de tabaco e outras drogas[AU]

RESUMO

OBJECTIVE: In response to the COVID-19 pandemic, restrictions were implemented, however, data indicates road crash rates have not decreased proportionately to the decline in traffic density. This study explored how speeding and phone use while driving (road behaviors associated with a high crash risk) changed as a result of COVID-19 restrictions in Queensland. METHODS: Two cross-sectional studies were conducted in Queensland, Australia to examine self-reported changes in speeding and phone use while driving before, during and after the easing of restrictions (while also considering exposure to the road and driving location). Study 1 (n = 351) was conducted between 12 May and 12 June 2020, when the majority of COVID-19 restrictions were enforced. Study 2 (n = 427) was conducted between 24 June and 12 August 2020, when restrictions were easing. RESULTS: The findings indicated, overall, self-reported speeding and phone use significantly decreased during restrictions (likely due to reduced travel), but not for those who continued to drive regularly. There was an additional, significant self-reported decrease in phone use while driving after restrictions were eased when compared to engagement during restrictions, which may (in part) be due to the simultaneous introduction of roadside mobile phone detection cameras. CONCLUSION: These findings highlight the importance of visible deterrence and provide a glimpse of possible consequences if there is a more sustained reduction in policing presence on roads.

RESUMO

BACKGROUND: Strengthening surveillance systems to collect near-real-time case-based data plays a fundamental role in achieving malaria elimination in the Greater Mekong Subregion (GMS). With the advanced and widespread use of digital technology, mHealth is increasingly taking a prominent role in malaria surveillance systems in GMS countries, including Myanmar. In Myanmar's malaria elimination program, an mHealth system called Malaria Case-based Reporting (MCBR) has been applied for case-based reporting of malaria data by integrated community malaria volunteers (ICMVs). However, the sustainability of such mHealth systems in the context of existing malaria elimination programs in Myanmar is unknown. METHODS: Focus group discussions were conducted with ICMVs and semi-structured in-depth interviews were conducted with malaria program stakeholders from Myanmar's Ministry of Health and Sports and its malaria program implementing partners. Thematic (deductive followed by inductive) analysis was undertaken using a qualitative descriptive approach. RESULTS: Technological and financial constraints such as inadequate internet access, software errors, and insufficient financial resources to support mobile phone-related costs have hampered users' access to MCBR. Poor system integrity, unpredictable reporting outcomes, inadequate human resources for system management, and inefficient user support undermined the perceived quality of the system and user satisfaction, and hence its sustainability. Furthermore, multiple parallel systems with functions overlapping those of MCBR were in use. CONCLUSIONS: Despite its effectiveness and efficiency in malaria surveillance, the sustainability of nationwide implementation of MCBR is uncertain. To make it sustainable, stakeholders should deploy a dedicated human workforce with the necessary technical and technological capacities; secure sustainable, long-term funding for implementation of MCBR; find an alternative cost-effective plan for ensuring sustainable system access by ICMVs, such as using volunteer-owned mobile phones for reporting rather than supporting new mobile phones to them; and find a solution to the burden of multiple parallel systems. TRIAL REGISTRATION: Not applicable.

RESUMO

Radiofrequency (RF) radiation from mobile phones has been classified as possibly carcinogenic to humans (2b) by IARC. However, to date, the discussion on whether mobile phone use is a cancer risk factor has not been solved. In this context of continuing uncertainty, it is important to continue to monitor cancer incidence trends. Annual incidence rates and directly age-standardized rates of selected cancers by sex and 5-year age groups for 1996 to 2017 for England were obtained from the UK Office for National Statistics. Interpretation in light of mobile phone use as a contributing risk factor was conducted for cancers of the brain, parotid gland, thyroid, and colorectal cancer, which have all been hypothesized to be associated with RF exposure. Brain and parotid gland cancers were updated by an additional 10 years following a previous publication, and continue to provide little evidence of an association with mobile phone use. Although mobile phone use as a potential risk factor contributing to increased incidence of colorectal or thyroid cancer could not be excluded based on these ecological data, it is implausible that it is an important risk factor for either. In the absence of clarity from epidemiological studies, it remains important to continue to monitor trends. However, for the time being, and in agreement with data from other countries, there is little evidence of an association between mobile phone use and brain or parotid gland cancer, while the hypotheses of associations with thyroid or colorectal cancer are similarly weak. © 2021 Bioelectromagnetics Society.

RESUMO

BACKGROUND: Cumulative trauma exposures can have a profound effect on women's health and well-being. Black immigrant women are disproportionately affected by cumulative trauma experiences that place them at risk for multiple health issues such as reproductive sexual health problems and HIV, or mental health problems such as PTSD. The trauma-informed internet and mobile phone-based Being Safe, Healthy, and Positively Empowered (BSHAPE) intervention was designed to comprehensively assess for cumulative traumatic experiences, for current safety, and to address women's co-occurring healthcare needs through educational, psychoeducational, and mindfulness-based stress-reduction components. PURPOSE: This paper describes the development, feasibility, acceptability, and preliminary evaluation of the computer and phone delivered BSHAPE intervention among adult Black immigrant women survivors of cumulative trauma. METHOD: Seventy women participated in the feasibility, acceptability, and preliminary evaluation of BSHAPE, with outcomes assessed at post-intervention. The feasibility and acceptability outcomes assessed were enrollment, adherence, and perceptions of the intervention. Preliminary evaluation outcomes included perceived stress, stress management, trauma coping self-efficacy, mindfulness, mental health (MH), HIV/STI risk, general empowerment, and empowerment related to safety. CONCLUSIONS: Findings suggest that a BSHAPE intervention is feasible and acceptable. Overall, women reported satisfaction with BSHAPE and provided suggestions for improvement. Women showed significant reduction in perceptions of stress, improved stress-management, enhanced self-efficacy, reduced HIV/STI risk, and improved MH, overall empowerment, as well as empowerment related to safety. The findings of this study will be useful in further refining BSHAPE and testing it in a full-scale randomized controlled trial. TRIAL REGISTRATION: NCT03664362.
